The vector control system of permanent magnet synchronous motor is taken as the research object. The traditional permanent magnet synchronous motor system adopts current hysteresis tracking PWM to speed regulation, which has some shortcomings in anti-interference ability and dynamic performance. In order to improve the anti-interference ability and dynamic performance of the motor, through the analysis of the principle of vector synthesis, a speed regulation system based on coordinate transformation and decoupling technology is designed, and voltage feedforward compensation and space vector pulse width technology (SVPWM) are adopted to improve the dynamic response of the system. Finally, Matlab/Simulink simulation platform is used to verify and analyze the anti-interference ability and tracking performance of the system. After experimental setting, the experimental results show that the designed motor control strategy can effectively adjust the expected speed of the motor system, and has good anti-interference ability and can effectively optimize the dynamic performance.
